The invention relates to horizontal chamber ovens intended for the production of gas and coke and having vertical heating flues in which a partition having perforations therein is arranged between the passages supplying the heating gas and the combustion air. The object of these perforations is to obtain a certain pre-cornbustion owing to the heating gas and the air tending to mutually pass 10 through the perforations, as it has been assumed hitherto. Now, it has been proved that the buoyancy, increased by the flame, of the preheated agents of combustion is so great. that any material mutual passage of gas and air does not take place and a satisfactory pie-combustion is thus not obtained. The invention has for its object to obviate this drawback which object substantially is obtained by so designing the detachably superimposed bricks which form the partition that a mutual passage of gas and air must take place through each brick and the possibility is given to vary at will according to the number of the bricks the degree of the pre-combustion aimed at by this mutual passage.

'The invention constitutes an adaption to horizontal chamber ovens of the measures described in my former application Ser. No.

159,611, which has resulted in Patent No. 1,787,490, issued January 6, 1931, and taken to obtain an eflicacious pre-combustion of gas andair in vertical chamber ovens. horizontal chamber ovens the application of the .chamber bricks described in and protected by this patent to the partitions of the horizontal flues that supply gas and air is impossible as most of the modern ovens do 40 not possess these horizontal flues and, be-

sides, a pre-oombu-stion within these flues would provoke only an undesired increased heating of the oven floor.

In order that the invention can be more easily understood, a preferred embodiment With is subdivided so as to form a plurality of heating. flues c. On the bottom end of each flue-c is provided a hole or perforation d to feed the heating gas and a hole or perforation 0 for the combustion air. The wall separating the holes 03 and 6 has mounted thereon a plurality of separating bricks f engaging Y one another by tongue and groove and the bricks being removable through an aperture (not shown) at the front end of the respective flue 0. Each of these bricks f has two oppositely inclined transverse slots f and 7 arranged side by side and covered at their lower ends by projections F. The combustion agents entering through the holes (1 and 7 e, are dammed by the projections and thereby enforced to stream in part through the inclined slots 7 and f and to-mix with one another.

As clearly seen it is possible to vary within wide limits the degree of pre-combustion aimed at by varying the number of the slotted bricks f of each pile. Y

I claim 1'. A gas and air mixer particularly for s0 coke oven flues having an air and a gas perforation, comprising a plurality of superposed bricks removably mounted in the flues and between the perforations,,each brick having passages therein from one side thereof to the other through which the air and gas flows from one side of the' flue to the other.
